There's a pretty good explanation of Polarizers and how to use them in current (Sept. 2002?) Pop Photography. The main reason I picked it up. It includes a description of the difference between Circular and Linear polarizers and how they interact with semi-silvered mirrors. I know from personal experience that the meter accuracy is adversely effected when using a linear polarizer.
